Richard Roe. that when a large number of these indicia are presented to the eye of the'pperator, such errors are very likely to occur.

r This possibility of error is attributable primar ily to the fact that heretofore no striking lineof demarcation has beenprovided between adjacent 1 V strips since the strips are'usually all of thesame base color and the-cutting. operation tends to form afillet along athe longitudinal edges of the.

face of the individual strips, which flllet partakes of the color of the face sheet.
